Electrical controls may also energizethe motors 154' and'i4 l to perform the clamping actions and pivotingactions respectively. Any well known arrangement of electrical controls'can' be used, andso such controls are not shown in the-drawings. The useof electrical motors and controls adds to the cost of the device, butmay render it automatic in operations a Fig. 4-of the drawings shows anembodiment wherein the weight of the object being lifted acts to, lockthe clamping jaws in place. in this arrangemenha guiding eyelet 258v anda pulley are aifozed to the horizontal member- 219; A pulley 262 is tothe vertical member 236, and a pulley 264' is afiixed to the trunnion23th A lifting cable26'6 is disposed'al-o'ng these pulleys and extendsthrough an opening in the center of'the stub shaft 242 whichextends'down through'thc bottom ofthe clamping bracket 24%. The cablethen xtends over pal-lay 263 and is afiixed to clamping bracket 240.When a coil of metal is disposed between the clamping jaw 250 and theclamping bracket 24%, a lifting force is applied to the upper end of thecable 266' by a crane. 'The lifting force pulls against the weightbf thecoil, and this lifting force is transferred through the cable 266 totightly engagev the jaws 24h? and'ZSdWith the coil. A balancingmechanism such as shown in Figs. 1-3 can also be used with thisembodiment.

From the foregoing description, it will be apparent that I have provideda novel and efficient' material-hark dlingdevice which is simple inarrangement and operation.

Having thus described my invention, I claim:

1. A material handling device, particularly adapted for 'use with acoiled workpiece such as a coil of metal, comprising a substantiallyLeshaped frame member which includes a horizontal leg and a verticallog; a trunnion in the lower portion of said vertical leg, the axis ofsaid trunnion being vdisposed at substantially a forty-fivedegree anglerelative to said vertical leg; a horizontal clamp bracket having a shaftthereon disposed in rotatable en-. gagement with said trunnion; avertical slide member having a horizontal clamp jaw rigidly aifixedthereto, said clamp jaw being slidable on said slide member; means formoving at least one of said clamp members so that the workpiece isgripped firmly between thesaid clamp members; said clamp members being.turnable to avertical position about the axis of said trunnion so that,the workpiece can be placed in either ahorizontaltorv adjacent the freeend of the horizontal leg on said frame;

and the free end of said flexible cable secured to a lifting device suchas a crane. j

3. A material handling device, particularly adapted for use with acoiled workpiece such as a coil of metal, comprising a substantaillyL-shaped frame member which includes a horizontal leg and a verticalleg; a trunnion in a the lower portion of said vertical leg, the axis ofsaid trunnion being disposed at substantially a forty-five degree anglerelative to said vertical leg; a horizontal clamping bracket having ashaft thereon disposed in rotatable engagement with said trunnion; avertical slide member having a horizontal clamp jaw rigidly aflixedthereto, said clamp jaw being slidable on said slide'mem ber; means formoving at least one of-said-clamp members so that the workpiece isgripped firmly between the said clamp members; said clamp members beingturnable to a-vertical position about the axis of said trunnion so thatthe workpiece can be placed in either a horizontal or vertical position;and means for afi'ixing the horizontal legof said frame member toalifting mechanism such asacrane, said means being movable along thehorizontal leg of said frame member to balance the material'handlingdevice. Y
